Accidentally bought the wrong phone and you wouldn’t let me return / exchange. Very disappointed and will be telling everyone I know not to buy Unihertz on social media and personal unless this is resolved.

Mein Tank 3 pro
Mein Tank 3 pro hat jetzt seit 4 Wochen einen Displayschaden ... Ich erhalte keinerlei Support nur bescheuerte Ratschläge und keinerlei Hilfe wer mir das Display ersetzen könnte ... Support Kontakt sehr minderwertig... Das Telefon selbst war super allerdings wird man bei Problemen im Stich gelassen

Terrible software support
Terrible software support, and when emailing them about a simple carrier update for the device they do not show any interest in updating the device past its OG software.

I can't believe I'm having to describe another massively negative review with this company. After my previous review, dated Dec 2024, I had to purchase a new phone as Jelly Star was unusable. In April, I started to really struggle holding the new phone (part of the reason for getting a tiny phone was ease of handling with a disability). I got the Jelly Star back out, performed a factory reset as advised by Unihertz, and started again. The same issue (screen not responding to touch) started occurring within 24 hours.
I've contacted Unihertz and asked to activate my warranty and obtain a new device. In fact, I've asked this several times. The customer service supervisor who was rude to me in December replied with a screenshot of my review, describing it as 'unacceptable'. In further emails, he has accused me of trying to use reviews to obtain money from the company. I wrote my review in December with the knowledge that I couldn't get a refund, and had no motive other than to document my experience for the knowledge of others - exactly what reviews are for. He has ignored my request to deal with another member of staff 3 times and continues to reply to my emails with the same unnecessary tone. I have asked to speak to a manager instead, but he's ignored this too. He asked for a video of the problem, and I advised that I'd already sent them a video in December and that the problem hasn't changed. He ignored me for over a week, and when I contacted them again to follow up, he said he was waiting for me to provide the video he requested, even though I'd already said I didn't need to send a second one.
I have asked multiple times now for a new device and it appears that I am being fobbed off. My warranty covers this, especially as I have provide evidence of the problem and followed their advice to attempt to fix it. I've even contacted their marketing department for help, but I've not heard back from them either at the time of writing.
Customers deserve better service than this company is providing. I've been reasonable with the company throughout the process, reading and rereading my emails before sending to check that they are fair, but have received multiple unpleasant emails in return. I've even tried calling their office to speak to someone in person but the line doesn't connect.
I'm not sure if I'm experiencing so many problems just because of this specific member of staff, but I originally asked for a new device before Easter and I'm still getting pushed back by the company with emails which are asking repeat questions and not achieving anything.
For anyone reading this review with the intention of buying a Unihertz device, please consider the experience of dealing with this company before you make a purchase. It's cost me money and so much time writing to them and waiting to hear back - not to mention frustration and upset reading the things they have written. The devices are cute and clearly have a place in the technology world, but dealing with their team has been incredibly draining and so unnecessary. I'm sure you'll be fine if nothing goes wrong with the device, but if you need help from customer service, expect it to be a rocky road.
UPDATE:
Unihertz reported my review, claiming that they are concerned that it's not genuine. They are fully aware that it is genuine, as I've been in communication with them since December. They have my Amazon order number and the identification numbers for my device. I've now provided this information to Trust pilot to enable this review to stand. Unihertz continue to ask for a further video of the problem with my phone, despite already having one. They also blocked my email address as spam after I asked to make a complaint about the member of staff who was being very unpleasant. If Unihertz don't want negative reviews, they need to treat their customers with respect and work to solve problems quickly, not fob people off for as long as possible.
Update as of 30th May:
The company are now ignoring me completely. So unprofessional, and hugely disappointing.
This is my second Unihertz Titan and both consistently kicky me out of whatever application I am in whenever I am trying to type in text and send me either to my home screen or to Google search.
I have contacted customer service about this and they act like they have no idea what I'm talking about, even though I now know that this is not just a malfunction specific to my first phone.
